Things You'll Need:
-
Step 1
Break out the concrete with the jackhammer at the lowest point on the concrete floor, preferably near an exterior wall. Remove a section 6 inches wider than the pit liner and dig the pit equal to the depth of the liner. Put the liner in the pit, fill with gravel and use concrete to seal the space between the edge of the pit and the floor.
-
Step 2
Drill a hole in the nearest exterior wall that matches the diameter of the discharge pipe provided with the sump pump assembly. Insert the discharge pipe into the hole and caulk around the pipe with a caulking gun.
-
Step 3
Connect the sump pump to the discharge fitting and set the pump into the bottom of the sump pit. Position the pump so that it is level, with its float within several inches of the liner's edge.
-
Step 4
Connect the discharge pipe to the discharge fitting on the sump pump with PVC pipe. Install the check valve provided with the sump pump between the discharge fitting and the PVC pipe extending from the discharge pipe. Seal the pipe connections with PVC cement.
-
Step 5
Tape the sump pump's power cord along the side of the discharge pipe using electrician's tape.
-
Step 6
Test the pump by pouring 5 gallons of water into the liner and turning on the pump.
